Base vector

AV:N/AC:L/Au:N/C:C/I:N/A:C

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.2.3

Description The issue is caused by an out-of-bounds access in the ath6kl wmi pstream timeout event rx and ath6kl wmi cac event rx functions in the file drivers/net/wireless/ath/ath6kl/wmi.c. This can allow a remote attacker to disclose protected information or cause a denial of service.

Recommendations For Linux kernel versions prior to 5.2.3, update to version 5.2.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the affected functions ath6kl wmi pstream timeout event rx and ath6kl wmi cac event rx until a patch is available.
